GigaManP2P is a management overlay for long-distance, high-speed optical backbones that span multiple administrative domains. GigaManP2P peers provide management services in a ubiquitous fashion, in particular services to negotiate, monitor and continuously enforce the required quality of service (QoS) for applications that span multiple domains. After detecting a QoS constraint violation trend, a proactive rerouting strategy is triggered based on redundant virtual circuits, allowing both full and partial rerouting. The system has been deployed on the Brazilian RNP backbone.
